Abstract
The utility model discloses an optical protecting film with nano-scale grooves, which comprises a protective layer and a bonding layer, wherein nano-scale curved grooves are formed on the outer surface of the protective layer, and are arranged in an array or at random; the density of the array is unlimited. As the nano-scale grooves are arranged on the bonding layer of the optical protecting film, the contact area between the layers is enlarged, the adhesive force between the layers is enhanced, and small-sized air bags formed during the jointing of the layers can improve the vibration resistance of the optical protecting film. The bonding layer has higher surface energy, can be adhered to the surface of a product well; and the phenomenon that adhesive residue caused by adhesive such as glue and the like can be avoided.
Description
Technical field
The present invention relates to a kind of film, be specifically related to optical protection layer, belong to field of packaging material with nano-scale groove.
Background technology
Optical elements such as prismatic lens because of its particular optical performance by being applied in the precision optical instruments such as microscope, visual telescope, medicine equipment more and more widely.At present, accurate goods are being processed, during carrying etc.,, all be to adopt the mode of interim adhesive surface protective membrane to realize the surface protection of clung body for fear of these accurate goods being brought damage etc.All the time, the surface protection surface that is employed in base material film mostly is provided with the bonding film of tackiness agent.But often because there be tens of microns concavo-convex in the surface of optical element; Therefore compare with other clung bodies; Very little with the contact area of tack coat, be difficult to stably to be pasted on prism surface, perhaps can because of bounding force is too strong can not be from smooth and easy peeling off on the adherend; Stay the phenomenon of residual film and cull when appearing at separating protective film, influence prismatical use and optic precision to a certain extent.In addition, the film anti-seismic performance also has tremendous influence to the goods of being protected, and also is one of urgent problem during present protective membrane design is produced.Therefore, be necessary to design and manufacture a kind of autohension and the excellent optical protection layer of shock resistance.
The utility model content
The purpose of the utility model is to overcome deficiency of the prior art, and the design protection performance is strong, peel off smooth and easy and can keep the excellent optical protection layer of prismatic lens cleaning surfaces, autohension and shock resistance.
To achieve these goals, technical scheme of the present invention provides a kind of optical protection layer with nano-scale groove, comprises protective layer and tack coat, it is characterized in that, said protective layer outside surface is provided with nano-scale groove.
In order to make protective membrane obtain different surface frictional force and anti-seismic performance, nano level curved surface groove arrangement mode is array or random mode, and density is not limit.
Simple to operate for production process, nano level curved surface groove is a semisphere, and said hemisphere diameter is 1～100nm.
In order to guarantee protective membrane material favorable mechanical performance, protective layer is at least a in new LDPE (film grade), high density polyethylene(HDPE), cast polypropylene, metallocene PE and the block polypropylene.
In order to make protective membrane have certain autohension, avoid the use of sizing agents such as glue and the cull phenomenon that causes, tack coat is an ethene Vinyl Acetate Copolymer multipolymer.
The advantage and the beneficial effect of the utility model are: in protective membrane, introduce nano-scale groove on the tack coat, can increase the frictional coefficient on protective membrane surface, can form small-sized air bag between the protective membrane when coating optical element, improve the protective membrane anti-seismic performance; Tack coat has than higher surface energy, can be good at sticking to product surface, effectively avoids the use of sizing agents such as glue and the cull phenomenon that causes, and this protective membrane satisfactory mechanical property.

Fig. 2 is the face of the overlooking structural representation of this practical optics protective membrane;
Fig. 3 is that another of this practical optics protective membrane overlooked the face structural representation.
Among the figure: 1, protective layer; 2, tack coat; 3, nano-scale groove.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
Referring to Fig. 1 and 2; On the coextrusion casting forcing machine, new LDPE (film grade) and ethene Vinyl Acetate Copolymer multipolymer are carried out co-extrusion modling, wherein, when on the coextrusion casting forcing machine, extruding; Extrude the nano level hemispherical groove that is the matrix form arrangement at the protective layer outside surface, the semisphere diameter is 1nm.
Embodiment 2
Referring to Fig. 1 and 3; On the coextrusion casting forcing machine block polypropylene and ethene Vinyl Acetate Copolymer multipolymer are carried out co-extrusion modling, wherein, when on the coextrusion casting forcing machine, extruding; At the nano level hemispherical groove of protective layer outside surface extrusion random alignment, semisphere diameter 50nm.
Referring to Fig. 1 and 3; Mixing material and ethene Vinyl Acetate Copolymer multipolymer with high density polyethylene(HDPE) and cast polypropylene on the coextrusion casting forcing machine carry out co-extrusion modling; Wherein, When on the coextrusion casting forcing machine, extruding, at the nano level hemispherical groove of protective layer outside surface extrusion random alignment, semisphere diameter 100nm.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
